C 与 C++中标准输入实现方式上的一点区别
以下是引用片段:
#include
int main()
...{
char a,b;
printf("Please input the first character:");
scanf("%c", &a);
printf("Please input the second character:");
scanf("%c", &b);
printf("The two characters are %c, %c", a, b);
return 0;
}
程序运行结果如下:
而下面这段程序却可以正常运行:
以下是引用片段:
#include
int main()
...{
char a;
int b;
printf("Please input the first character:");
scanf("%c", &a);
printf("Please input the second integer:");
scanf("%d", &b);
printf("The two characters are %c, %d", a, b);
return 0;
}
运行结果如下:
当时对这个问题很困惑,时间一长就慢慢淡忘了。
